IMPROVEMENT IN APPARATUS FOR SMOKING MEATS.

Specification forming part of Letters Patent No. l 5,452, dated July 29,1856.

To all rwhom 'it may concern:

Beit known that I, JOHN WRIGHll, of the city of Wilmington, in' thecounty of New Oastle and State of Delaware, have invented a new andImproved Mode ot' Smoking Meats, Fish, Ste.; and I do hereby declarethat the following is a full and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of referencemarked thereon.v

The nature of .my invention consists in providing outside of thebuilding used for smoking (A) furnaces with a grate and fireplate soformed as to cause all the smoke generated to pass into the house, andin setting up or building` inclined flues with smoke Stoppers andspreaders, so that the smoke generated will pass throughout the house,smoking the meat, Src., evenly in any part of the building, and in lesstime than is generally taken for such purposes, besides preventing dustor ashes from falling` upon the meat, &c., besides preventing redamaging the building or heating the meat. y

Io enable others skilled in th'e art to make and use my invention, Iwill proceed to describe its construction and operation.

In building the smoke-house A, I lay the foundation of` stone or bricktwo feet deep,

twelve inches thick, and nine feet square. I then run up the walls fteenfeet high on the lowest or furnace side of the building, and on thehighest or entrance side sixteen feet, giving the roof a pitch of aboutone foot in eight.

The walls may be of thethickness of eight or nine inches 5 but four anda half inches are thick enough for the smallest-sized buildings.

In running up my walls I set in a piece of three-by-four scantling,about nine feet from the floor ofthe building, on the inside, runningacross the front and back walls. I then set in a like piece about twelveinches from the iirst one, and others, until I get to the top of thelowest wall.

For smoking herring I use three or more pieces of the saine-sizedscantling cut so as to slip between the walls, their ends resting uponthe pieces c a a, c, built in the walls. I use like movable scantlingslled with hooks to hang meats, Src., upon. As to thel material forrooting, a shingle, board, or pebble root' will answer.

I v entilate the house by a door in the root' b, which 1n this sizedhouse isV twelve by fifteen inches in size, which I open or close bymeans of a rod. By opening this door the smokepasses oft1 and sufficientlight is admitted for all purposes.

In constructing the furnaces A A A, I pave with brick, about eight feetfrom the smokehouse, the whole length of the building. I make thefurnaces about three feet high, with the end and division walls four anda half inches thick, (marked 1 l l l in the drawing 13;) the grates B BB twenty inches wide, twenty-eight inches deep; the doors of castiron,eleven by twelve inches. The whole length and breadth of the grateunderneath the thick cast-iron or sheet-iron rests upon the walls andforms an air or smoke chamber, C, in size four by twenty-two inches, bywhich arrangement the draft is increased and all the smoke generatedpasses into theinclined hues D D D, and none is lost, as is often thecase otherwise, when the contents of the furnace drop into theash-chamber beneath the grate.

The inclined ilues in the first place connect with smoke-chamber C,passing through the wall of the house, and are eight inches square aboutsix inches from the top of the pavement. I build the wall E across thebuilding four and a half inches thick, leaving holes eight inches indiameter for sheet-iron collars eight inches in length. The flues D D D,which are composed of brick, earthenware, or iron, or otherincombustible material, I lay after having packed in earth between thewalls until I obtain the desired inclination. I then, provided -I buildof brick, lay a header-course of brick upon the earth from the bottom ofthe entrance of the ue to the opening in the inner wall, E. The lengthof iues should be three-fourths the width of the house--in a houseA ofthis size, (about eight feet inside,) say lsix feet. I lay the rstcourse of brick without mortar,

.the course to be laid lengthwise against the row ofheaders also withoutniortar; then three other courses laid in mortar/'on each side ofthefirst course of headers. The last course I draw over a little, so as togive the last course ot' headers a bearing of half an inch on each side,which forms the ilue. The brick flue is easier cleanedthan any other.

I leave an opening fourteen inches from the Wall, and build up withbrick level With the pavement, and build a sheet-iron collar therein. Ialso make another upright iiue four and a half feet from the first, (thefirst marked F, the second G, in the drawing.) I then iill in and coverthe flues with earth packed, and pave the top with brick, giving thepavement an ascent of about siX inches from the inner Wall to the Wallof the house. This pavement I lay even with the upright or verticaliiues or pipes F G.

The openings in the ues I stop With caps of sheet-iron when but littlesmoke is needed, and use the smoke-spreader, which will it any opening.This smoke-spreader, which is shown at or upon the vertical iiue G inthe plan A, consists of a circular piece of tin or iron supported bywires attached to a rim made to fit the collars or openings, and isabout twelve or fteen inches in diameter, and set about eighteen inchesabove the rim to which it is attached. This little spreader `:vill breakthe column of smoke arising and spread it all over the house.

My building, nine feet square, fifteen feet high, with these flues, willsmoke ve thousand herrings in three days, at a cost of seventyve cents.These furnaces and flues can be erected or attached to any smoke-housealready built, and the house not likely to take iire from the furnacesor sparks from the pipes, although the building be frame.
